PREFACE TO THE SECOND EDITION
The studies of the trees of North America (exclusive of Mexico) which have been carried
on by the agents and correspondents of the Arboretum in the sixteen years since the publi-
cation of the Manual of the Trees of North America have increased the knowledge of
the subject and made necessary a new edition of this Manual. The explorations of these
sixteen years have added eighty-nine species of trees and many recently distinguished
varieties of formerly imperfectly understood species to the silva of the United States, and
made available much additional information in regard to the geographical distribution of
American trees. Further studies have made the reduction of seven species of the first edi-
tion to varieties of other species seem desirable; and two species, Amelanchier ohovalis and
Cercocarpus parvifolius, which were formerly considered trees, but are more properly
shrubs, are omitted. The genus Anamomis is now united with Eugenia; and the Arizona
Pinus strobiformvi Sarg. (not Engelm.) is now referred to Pinus flexilis James.
Representatives of four Families and sixteen Genera which did not appear in the first
edition are described in the new edition in which will be found an account of seven hundred
and seventeen species of trees in one hundred and eighty-five genera, illustrated by seven
hundred and eighty-three figures, or one hundred and forty-one figures in addition to those
which appeared in the first edition.
An International Congress of Botanists which assembled in Vienna in 1905, and again in
Brussels in 1910, adopted rules of nomenclature which the world, with a few American ex-
ceptions, has now generally adopted. The names used in this new Manual are based on
the rules of this International Congress. These are the names used by the largest number
of the students of plants, and it is unfortunate that the confusion in the names of American
trees must continue as long as the Department of Agriculture, including the Forest Service
of the United States, uses another and now generally unrecognized system.
The new illustrations in this edition are partly from drawings made by Charles Edward
Faxon, who died before his work was finished; it was continued by the skillful pencil of
Mary W. Gill, of Washington, to whom I am grateful for her intelligent cooperation.
It is impossible to name here all the men and women who have in the last sixteen years
contributed to this account of American trees, and I will now only mention Mr. T. G. Har-
bison and Mr. E. J. Palmer, who as agents of the Arboretum have studied for years the
trees of the Southeastern States and of the Missouri-Texas region. Professor R. S. Cocks, of
Tulane University, who has explored carefully and critically the forests of Louisiana, and
Miss Alice Eastwood, head of the Botanical Department of the California Academy of
Sciences, who has made special journeys in Alaska and New Mexico in the interest of this
Manual. Mr. Alfred Rehder, Curator of the Herbarium of the Arboretum, has added to
the knowledge of our trees in several Southern journeys; and to him I am specially indebted
for assistance and advice in the preparation of the keys to the diflFerent groups of plants
found in this volume.
This new edition of the Manual contains the results of forty-four years of my continuous
study of the trees of North America carried on in every part of the United States and in
many foreign countries. If these studies in any way serve to increase the knowl-
edge and the love of trees I shall feel that these years have not been misspent.

PREFACE
In this volume I have tried to bring into convenient form for the use of students the in-
formation concerning the trees of North America which has been gathered at the Arnold
Arboretum during the last thirty years and has been largely elaborated in my SUva of
North America.
The indigenous trees of no other region of equal extent are, perhaps, so well known as
those that grow naturally in North America. There is, however, still much to be learned
about them. In the southern states, one of the most remarkable extratropical regions in
the world in the richness of its arborescent flora, several species are still imperfectly known,
while it is not improbable that a few may have escaped entirely the notice of botanists; and
in the northern states are several forms of Crataegus which, in the absence of suflScient in-
formation, it has been found impracticable to include in this volume. Little is known as
yet of the silvicultural value and requirements of North American trees, or of the diseases
that affect ihem; and one of the objects of this volume is to stimulate further investigation
of their characters and needs.
The arrangement of families and genera adopted in this volume is that of Engler &
Prantl's Die Natiirlichen Pfianzenfamilien, in which the procession is from a simpler to a
more complex structure. The nomenclature is that of The SUva of North America. De-
scriptions of a few species of Crataegus are now first published, and investigations made
since the publication of the last volume of The SUva of North America, in December, 1902,
have necessitated the introduction of a few additional trees described by other authors, and
occasional changes of names.
An analytical key to the families, based on the arrangement and character of the leaves,
will lead the reader first to the family to which any tree belongs; a conspectus of the genera,
embodying the important and easily discovered contrasting characters of each genus and
following the description of each family represented by more than one genus, will lead him
to the genus he is trying to determine; and a similar conspectus of the species, following the
description of the genus, will finally bring him to the species for which he is looking. Fur-
ther to facilitate the determination, one or more letters, attached to the name of the species
in the conspectus following the description of the genus, indicate in which of the eight re-
gions into which the country is divided according to the prevailing character of the arbores-
cent vegetation that species grows (see map forming frontispiece of the volume). For
example, the northeastern part of the country, including the high Appalachian Mountains
in the southern states which* have chiefly a northern flora, is represented by (A), and a per-
son wishing to learn the name of a Pine-tree or of an Oak in that region need occupy him-
self only with those species which in the conspectus of the genus Quercus or Pinus are
followed by the letter (A), while a person wishing to determine an Oak or a Pine-tree in
Oregon or California may pass over all species which are not followed by (G), the letter
which represents the Pacific coast region south of the state of Washington.
The sign of degrees (°) is used in this work to represent feet, and the sign of minutes (')
inches.
The illustrations which accompany each species and important variety are one half the
size of nature, except in the case of a few of the large Pine cones, the flowers of some of the
• ••
Vm PREFACE
Magnolias, and the leaves and flower-clusters of the Palms. These are represented as less
than half the size of nature in order to make the illustrations of uniform size. These illus-
trations are from drawings by Mr. Faxon, in which he has shown his ulfeual skill and experi-
ence as a botanical draftsman in bringing out the most important characters of each species,
and in them will be found the chief value of this Manual. For aid in its preparation I am
indebted to him and to my other associates, Mr. Alfred Rehder and Mr. George R. Shaw,
who have helped me in compiling the most diflficult of the keys.

Pinus is widely distributed through the northern hemisphere from the Arctic CircU
to the West Indies, the mountains of Central America, the Canary Islands, northern
Africa, the Philippine Islands, and Sumatra. About sixty-six species are recognized. Of
exotic species the so-called Scotch Pine, Pinv^ sylvestris L., of Europe and Asia, the Swiss
Stone Pine, Pinus cembra L., and the Austrian Pine and other forms of Pinus nigra
Arnold, from central and southern Europe, are often planted in the northeastern states
and Pinus Pinaster Ait., of the coast region of western France and the Mediterranean
Basin is successfully cultivated in central and southern California. Pinus is the classica'
name of the Pine-tree.
The North American species can be conveniently grouped in two sections. Soft Pir -
and Pitch Pines.

Picea is widely distributed through the colder and temperate regions of the northern hem-
isphere, some species forqiing great forests on plains and high mountain slopes. Thirty-
seven species are now recognized, ranging from the Arctic Circle to the slopes of the southern
Appalachian Mountains and to those of northern New Mexico and Arizona in the New
World, and to central and southeastern Europe, the Caucasus, the Himalaya^ western
China, Formosa and Japan. Of exotic species the so-called Norway Spruce, Picea Abies
Karst., one of the most valuable timber-trees of Europe, has been largely planted for
ornament and shelter in the eastern states, where the Caucasian Picea orientalis Can*.,
and some of the Japanese species also flourish.
Picea was probably the classical name of the Spruce-tree.

nectives terminating in short spurs, the female "terminal or in the axils of upper leaves,
composed of spirally arranged ovate rounded scales much shorter than their acutely 2-lobed
bracts, with midribs produced into elongated slender tips. Fruit an ovoid-oblong acute
pendulous cone maturing in one season, with rounded concave rigid scales persistent on
the axis of the cone after the escape of the seeds, and becoming dark red-brown, much
shorter than the 2-lobed bracts with midribs ending in rigid woody linear awns, those at the
base of the cone without scales and becoming linear-lanceolate by the gradual suppression
of their lobes. Seeds nearly triangular, full, rounded and dark-colored on the upper side
and pale on the lower side, shorter than their oblong wings infolding the upper side of the
seeds in a dark covering; outer seed-coat thick and crustaceous, the inner thin and mem-
branaceous; cotyledons 6-12, much shorter than the inferior radicle.
Pseudotsuga is confined to western North America, southern Japan, southwestern China

the Himalayas, Asia Minor, and the highlands of northern Africa. Thirty-three species
are now recognized. Several exotic species are cultivated in the northern and eastern
states; of these the best known and most successful as ornamental trees are Abies Nord-
manniana, Spach, of the Caucasus, Abies cilicica Carr., of Asia Minor, Abies cephalonica
Loud., a native of Cephalonia, Abies Veitchii Lindl., and Abies homolepis S. & Z., of

forms appearing sometimes on the same branch or on different branches of the same tree.
Flowers minute, solitary, monoecious, appearing in early spring from buds formed the
previous autumn, the male terminal in the axils of upper leaves, oblong or ovoid, sur-
rounded by an involucre of numerous imbricated ovate, acute, and apiculate bracts, with
numerous spirally disposed filaments dilated into ovoid acute subpeltate denticulate connec-

short ovule-bearing scales rounded above and bearing below their upper margin in 2 rows
5-7 ovules at first erect, becoming reversed. Fruit an ovoid or short-oblong pendulous
cone maturing during the first or second season, persistent after the escape of the seeds,
its scales formed by the enlargement of the united flower and ovuliferous scales, becoming
woody, bearing large deciduous resin-glands, gradually enlarged upward and widening
at the apex into a narrow thickened oblong disk transversely depressed through the middle
and sometimes tipped with a small point. Seeds 5-7 under each scale, oblong-ovoid, com-

of tips; seeds with wings nearly J' long, |' wide.
A tree, with a tall lobed gradually tapering trunk, rarely 12° and generally 4°-5° in di-
ameter above the abruptly enlarged strongly buttressed usually hollow base, occasionally
150° tall, in youth pyramidal, with slender branches often becoming elongated and slightly
pendulous, in old age spreading out into a broad low rounded crown often 100° across, and
slender branchlets light green when they first appear, light red-brown and rather lustrous
during their first winter, becoming darker the following year, the lateral branchlets de-

ciduous, 3'-4' long, spreading at right angles to the branch, or in the form with acicular
leaves pendulous or erect and often 6' long. Bark l'-2' thick, light cinnamon-red and
divided by shallow fissures into broad flat ridges separating on the surface into long thin
closely appressed fibrous scales. Wood light, soft, not strong, very durable, easily worked,
light or dark brown, sometimes nearly black; largely used for construction, railway-ties,
posts, fences, and in cooperage.
Distribution. River swamps usually submerged during several months of the year,
low wet banks of streams,- and the wet depressions of Pine-barrens from southern New
Jersey and southern Delaware southward generally near the coast to the Everglade Keys,
southern Florida, and through the Gulf-coast region to the valley of Devil River, Texas,
through Louisiana to southern Oklahoma, through southern and western Arkansas to
southeastern Missouri, and through western and northern Mississippi to Tishomingo
County, and in western Tennessee and Kentucky to southern Illinois and southwestern
Indiana; most common and of its largest size in the south Atlantic and Gulf states, often
covering with nearly pure forests great river swamps. From the coast of North Carolina to
southern Florida, southern Alabama and eastern and western Louisiana the form with
acicular leaves ( Taxodium distichum var. imbricarium, Croom.) is not rare as a small tree in
Pine-barren ponds and swamps.
Taxodium distichum var. imbricarium is now usually and rightly considered a distinct
species for which the correct name is Taxodium ascendens Brong.; the extension of its range
into western Louisiana is not supported by specimens.
Often cultivated as an ornamental tree in the northern United States, and in the coun-
tries of temperate Europe, especially the var. imbricarium (as Glyptostrobus sinensis Hort.
not Endl).
9. LIBOCEDRUS EndL

disposed in one horizontal plane and forming an open 2-ranked spray and often ultimately
deciduous, straight-grained durable fragrant wood, and naked buds. Leaves scale-like, in
4 ranks, on leading shoots nearly equally decussate, closely compressed or spreading, dying
and becoming woody before falling, on lateral flattened branchlets much compressed,
conspicuously keeled, and nearly covering those of the other ranks; on seedling plants
linear-lanceolate and spreading. Flowers monoecious, solitary, terminal, the two sexes on
different branchlets; male oblong, with 12-16 decussate filaments dilated into broad con-
nectives usually bearing 4 subglobose anther-cells; female oblong, subtended at base by
several pairs of leaf-life scales slightly enlarged and persistent under the fruit, composed
of 6 acuminate short-pointed scales, those of the upper and middle ranks much larger
than those of the lower rank, ovate or oblong, fertile and bearing at the base of a minute
accrescent ovuliferous scale 2 erect ovules. Fruit an oblong cone maturing in one season,

the third pair confluent into an erect partition. Seeds in pairs, erect on the base of the
scale; seed-coat membranaceous, of 2 layers, produced into thin unequal lateral wings, one
narrow, the other broad, oblique, nearly as long as the scale; cotyledons 2, about as long
as the superior radicle.
Libocedrus is confined to western North America, western South America, where it is
distributed from Chili to Patagonia, New Zealand, New Caledonia, New Guinea, Formosa,
and southwestern China. Eight species are distinguished.
Libocedrus, from Xi^ds and Cedrus, relates to the resinous character of these trees.

Fig. 65
slender branches erect at the top of the tree, below sweeping downward in bold curves,
forming a narrow open feathery crown becoming in old age irregular in outline by the
greater development of a few ultimately upright branches forming secondary stems, and
stout branchlets somewhat flattened and light yellow-green at first, turning light red-brown
during the summer and ultimately broWn more or less tinged with purple, the lateral branch-
lets much flattened, 4'-6' long, and usually deciduous at the end of the second or third
season. Bark ^'-1' thick, bright cinnamon-red, and broken into irregular ridges covered
with closely appressed plate-like scales. Wood light, soft, close-grained very durable in
contact with the soil, light reddish brown, with thin nearly white sap wood; often injured

ern part of the state; on the Sierra del Pimal and the San Pedro Martir Mountains,
Lower California; most abundant and of its largest size on the Sierra Nevada, of central
California at elevations of 5000°-7000° above the sea.
Often cultivated as an ornamental tree in western and central Europe, where it grows
rapidly and promises to attain a large size; occasionally planted in the New England and
middle Atlantic states; hardy in the Arnold Arboretum.

Thuja is confined to northeastern and northwestern America, to Japan, Korea and
northern China. Five species are recognized. (X the exotic species the Chinese Thuja
orientalis, L., with many varieties produced by cultivation, is frequently planted in the
United States, especially in the south and west, for the decoration of gardens, and is dis-
tinguished from the other species by the thick umbonate scales of the cone, only the 4
lower scales being fertile, and by the thick rounded dark red-purple seeds without wings.
Thuja is the classical name of some conJi'erous tree.

Taxus with six or seven species, which can be distinguished only by their leaf characters
and habit, is widely distributed through the northern hemisphere, and is found in eastern
North America where two species occur, in Pacific North America, Mexico, Europe, north-
ern Africa, western and southern Asia, China, and Japan. Of the exotic species the Euro-
pean, African, and Asiatic Taxus baccata L., and its numerous varieties, is often cultivated
in the United States, especially in the more temperate parts of the country, and is replaced
with advantage by the hardier Taxus cuspidata S. & Z., of eastern Asia in the northern
states, where the native shrubby Taxus canadensis Marsh, with monoBcious flowers is
sometimes cultivated.

Thrinax is confined to the tropics of the New World and is distributed from southern
Florida through the West Indies to the shores of Central America. Seven or eight species
are now generally recognized.
The wood of the Florida species is light and soft, with numerous small fibro-vascular
bundles, the exterior of the stem being much harder than the spongy interior. The stems
are used for the piles of small wharves and turtle-crawls, and the leaves for thatch, and in
making hats, baskets, and small ropes.
Thrinax, from dpiva^, is in allusion to the shape of the leaves.

and probable hybrids are recognized. Of the species which inhabit the territory of the
United States nine assume the habit and attain the size of small trees. The root-stalks
of Yucca are used as a substitute for soap, and ropes, baskets, and mats are made from
the tough fibres of the leaves. Many of the species are cultivated, especially in countries
of scanty rainfall, for their great clusters of beautiful flowers, or in hedges tcf protect gar-
dens from cattle.
The generic name is from the Carib name of the root of the Cassava.

Japan in the Old World. Of the thirty-four species now generally recognized fifteen are
found in North America. The wood of many of the American species is employed in large
quantities for paper-making, and several species furnish wood used in construction and in
the manufacture of small articles of woodenware. The bark contains tannic acid and is
used in tanning leather and occasionally as a tonic, and the fragrant balsam contained in
the buds of some species is occasionally used in medicine. The rapidity of their growth,
t^eb hardiness and the ease with which they can be propagated by cuttings, make many of
the species useful as ornamental trees or in wind-breaks, although planted trees often suffer
severely from the attacks of insects boring into the trunks and branches. Of the exotic
species, the Abele, or White Poplar, Populus alba L., of Europe and western Asia, and its
fastigiate form, and the so-called Lombardy Poplar, a tree of pyramidal habit and a form
of the European and Asiatic Populus nigra L., and one of its hybrids, have been largely
planted in the United States.
Pojmlus, of obscure derivation, is the classical name of the Poplar.

Hills of South Dakota, northwestern Nebraska (basin of Hat Creek), and in Colorado; the
characteristic tree on the streams of the prairie region of British America, attaining its
greatest size on the islands and banks of the Peace, Athabasca, and other tributaries of the
Mackenzie; common in all the region near the northern boundary of the United States
from Maine to the western limits of the Atlantic forests; the largest of the sub-Arctic

been long cultivated in the northeastern part of the country and has sometimes escaped
from cultivation and formed groves of considerable extent, as on the banks of Cullasagee
Creek on the western slope of the Blue Ridge in Macon County, North Carolina. The
fact that only one sex is known suggests hybrid origin but of obscure and possibly partly
of foreign origin.

2 minute opposite lateral buds alternate with 2 small scale-like caducous leaves coated
with long jmle or rufous hairs. Leaves variously folded in the bud, alternate, simple,
lanceolate, obovate, rotund or linear, penniveined ; petioles sometimes glandular at
the apex, and more or less covering the bud, in falling leaving U-shaped or arcuate
elevated leaf-scars displaying the ends of 3 small equidistant fibro- vascular bundles;
stipules oblique, serrate, small and deciduous, or foliaceous and often persistent, generally
large and conspicuous on vigorous young branches, leaving in falling minute persistent
scars. Flowers in sessile or stalked aments, terminal and axillary on leafy branchlets;
scales of the ament lanceolate, concave, rotund or obovate, entire or glandular-dentate,
of uniform color or dark-colored toward the apex, more or less hairy, deciduous or per-
sistent; disk of the flower nectariferous, composed of an anteriof and posterior or of a single
posterior gland-like body; stamens 3-12 or i or 2, inserted on the base of the scale, with slender
filaments free or rarely united and usually light yellow, glabrous, or hairy toward the base,
and small ovoid or oblong anthers generally rose-colored before anthesis, becoming orange

tains, and the Arctic and sub-Arctic regions of the northern hemisphere, ranging south
in the New World, with a few species, through the West Indies and Central America to
Brazil, and the Andes of Chili, and in the Old World to Madagascar, southern Africa,
the Himalayas, Burmah, the Malay peninsula, Java, and Sumatra. Of the 160 or 170 species
which are now recognized about seventy are found in North America. Of these twenty-
four attain the size and habit of trees, the others being small and sometimes prostrate
shrubs. Of exotic species, Salix alba, L., and Salixjragilis L., important European timber-
trees, are now generally naturalized in the northeastern states. The flexible tough branches
of several species are used in making baskets; the bark is rich in tannic acid and is used in
tanning leather and yields salicin, a bitter principle valuable as a tonic. Many of the
species are cultivated as ornamental trees.
Salix is the classical name of the Willow-tree.

erect, with a thin coat, without albumen; embryo straight; cotyledons plano-convex, fleshy;
radicle short, superior, turned away from the minute basal hilum.
The family consists of the genus Myrica L., of about thirty or forty species of small
trees and shrubs, widely distributed through the temperate and warmer parts of both
hemispheres. Of the seven North American species three are trees. Wax is obtained
from the exudations of the fruit of several species. The bark is astringent, and sometimes
used in medicine, in tanning, and as an aniline dye. Myrica rubra Sieb and Zucc, of
southern Japan and China, is cultivated for its succulent aromatic red fruit.
The generic name is probably from the ancient name of some shrub, possibly the Tarn*
arisk.

Eleven species are known. Of exotic species Juglans regia L., an inhabitant probably
originally of China, is cultivated in the middle Atlantic and southern states and largely
in California for its edible nuts, which are an important article of commerce. The wood
of several species is valued for the interior finish of houses and for furniture.
Juglans, from Jupiter and glands, is the classical name of the Walnut-tree.

lateral branchlets, their scales closely imbricated, oblong-ovate, 3-lobed, light yellow, often
tinged with red above the middle, accrescent, becoming brown and woody at maturity,
and forming sessile or stalked erect or pendulous short or elongated strobiles usually ripen-
ing in the autumn, deciduous with the nuts from the slender rachis; calyx of the pistillate
flower 0; ovary sessile, compressed, with styles stigmatic at apex. Nut minute, oval or
obovoid, compressed, bearing at the apex the persistent stigmas, marked at the base by
a small pale scar, the outer coat of the shell produced into a marginal wing interrupted at
1 the apex.
Betula is widely distributed from the Arctic circle to Texas in the New World, and to
southern Europe, the Himalayas, China, and Japan in the Old World, some species form-
ing great forests at the north, or covering high mountain slopes. Of the twenty-eight or
thirty species now recognized twelve are found in North America; of these nine are trees.
Of exotic species the European and Asiatic Betula pendula Roth, in a number of forms is a
common ornamental tree in the northern states, where several of the Birch-trees of eastern
Asia also flourish. Many of the species produce wood valued by the cabinet-maker, or used
in the manufacture of spools, shoe-lasts, and other small articles. The thin layers of the
bark are impervious to water and are used to cover buildings, and for shoes, canoes, and
boxes. The sweet sap provides an agreeable beverage.
Betula is the classical name of the Birch-tree.

without change of color; stipules of all but the first leaf ovate, acute, and scarious. Flowers
vernal, or rarely opening in the autumn from aments of the year, in 1-3-flowered cymes
in the axils of the peltate short-stalked scales of stalked aments formed in summer or
autumn in the axils of the last leaves of the year or of those of minute leafy bracts; stamin-
ate aments elongated, pendulous, paniculate, naked and erect during the winter, each
staminate flower subtended by 3-5 minute bractlets adnate to the scales of the ament, and
composed of a 4-parted calyx, and 1-3 or usually 4 stamens inserted on the base of the calyx
opposite its lobes, with short simple filaments; pistillate aments ovoid or oblong, erect,
stalked, produced in summer in the axils of the leaves of a branch developed from the
axils of an upper leaf of the year, and below the staminate inflorescence, inclosed at first
in the stipules of the first leaf, emerging in the autumn and naked during the winter, or
remaining covered until early spring; pistillate flowers in pairs, each flower subtended by
2-4 minute bractlets adnate to the fleshy scale of the ament becoming at maturity thick
and woody, obovate, 3-5-lobed or truncate at the thickened apex, forming an ovoid or
subglobose strobile persistent after the opening of its closely imbricated scales; calyx 0;
ovary compressed; nut minute, bright chestnut-brown, ovoid to oblong, flat, bearing at
the apex the remnants of the style, marked at the base by a pale scar, the outer coat of
the shell produced into lateral wings often reduced to a narrow membranaceous border.
Alnus inhabits swamps, river bottom-lands, and high mountains, and is widely and gen-
erally distributed through the northern hemisphere, often forming the most conspicuous
feature of vegetation on moimtain slopes, ranging at high altitudes southward in the New
World through Central America to Colombia, Peru, and Bolivia, and to upper Assam and
Japan in the Old World. Of the eighteen or twenty species now recognized nine are North
American; of these, six attain the size and habit of trees. Of the exotic species, Alnus
cvlgaris Hill., a common European, north African, and Asiatic timber-tree, was introduced
many years ago into the northeastern states, where it has become locally naturalized.
The wood of Alnus is very durable in water, and the astringent bark and strobiles are used
in tanning leather and in medicine. ^
Alnus is the classical name of the Alder.

Trees, with watery juice, slender terete branchlets marked by numerous usually pale
lenticels, alternate stalked penniveined leaves, and narrow mostly deciduous stipules.
Flowers monoecious, the staminate in unisexual heads or aments, composed of a 4-8-lobed
calyx, and 4 or 8 stamens, with free simple filaments and introrse 2-celled anthers, the cells
parallel and contiguous, opening longitudinally; the pistillate solitary or clustered, in ter-

from the tip of the hairy dissepiment of the ovary pushed by the growth of the seed into
one of the angles of the nut; cotyledons sweet, oily, plano-convex.
Fagus as here limited is confined to the northern hemisphere, with a single American
species and seven Old World species; of these one is widely distributed through Europe,
another is found in the Caucasus, and the others are confined to eastern temperate Asia.
Of exotic species, the Eiu*opean Fagus sylvatica L., an important timber-tree, is frequently
planted for ornament in the eastern states in several of its forms, especially those with
purple leaves, and with pendulous branches. The wood of Fagus is hard and close-grained.
The sweet seeds are a favorite food of swine, and yield a valuable oil.
Fagus is the classical name of the Beech-tree.

conspicuous pale circular or oval thickened scar, its shell lined with rufous or hoary tomen-
tum. Seed usually solitary by abortion, dark chestnut-brown, marked at apex by the
abortive ovules, with thick and fleshy more or less undulate ruminate sweet farinaceous
cotyledons.
Castanea is confined to the northern hemisphere, and is widely distributed through east-
ern North America, southern Europe, northern Africa, southwestern Asia, and central and
northern China, Korea, and Japan. Seven species are distinguished. In the countries of
the Mediterranean Basin much attention has been given to improving the fruit of the native
species Castanea sativa Mill., which is occasionally planted in the middle United States;
in Japan the seeds of Castanea crenata S. & Zucc. in many varieties and in China those of
Castanea mollissima Bl. are important articles of food. Castanea produces coarse-grained
wood very durable in contact with the soil, and rich in tannin. Chestnut-trees suffer in
the eastern United States from the attacks of a fungus, Endothia parasitica Anders, which
has nearly exterminated them in many parts of the country.
Castanea is the classical name of the Chestnut-tree.

Quercus inhabits the temperate regions of the northern hemisphere and high altitudes
within the tropics, ranging in the New World southward to the mountains of Colombia
and in the Old World to the Indian Archipelago. Two hundred and seventy-five species
have been described; of the North American species fifty-four are large or small trees.
Of exotic species, the European Quercus robur L., and Quercus sessiliflora Salisb., have been
frequently cultivated as ornamental trees in the eastern United States, where, however,
they are usually short-lived and unsatisfactory. Many of the species are important
timber-trees; their bark is often rich in tannin and is used for tanning leather, and all pro-
duce wood valuable for fuel and in the manufacture of charcoal.
Quercus is the classical name of the Oak-tree.

with persistent ring-like scars. Leaves simply or doubly serrate; stipules linear, lan-
ceolate to obovate, entire, free or connate at base, scarious, inclosing the leaf in the bud,
caducous. Flowers from axillary buds near the ends of the branches similar to but larger
than the leaf-buds, the outer scales sterile, the inner bearing flowers and rarely leaves.
Flowers perfect, jointed on slender bibracteolate pedicels from the axils of linear acute
scarious bracts, in pedunculate or subsessile fascicles or cymes sometimes becoming race-
mose, appearing in early spring before the leaves in the axils of those of the previous year,
or autumnal in the axils of leaves of the year; calyx campanulate, 5-9-lobed, membranaceous,
marcescent; stamens 5 or 6 inserted under the ovary; filaments filiform or slightly flat-
tened, erect in the bud, becoming exserted; anthers oblong, emarginate, and subcordate;
ovary sessile or stipitate, compressed, crowned by a simple deeply 2-lobed style, the
spreading lobes papillo-stigmatic on the inner face, usually 1-celled by abortion, rarely
2-celled; ovule amphitropous; micropyle extrorse, superior. Fruit an ovoid or oblong, often
oblique, sessile or stipitate samara surrounded at base by the remnants of the calyx, the
seminal cavity compressed, slightly thickened on the margin, chartaceous, produced into
a thin reticulate-venulose membranaceous light brown broad or rarely narrow wing naked
or ciliate on the margin, tipped with the remnants of th? persistent style, or more or

less deeply notched at apex, and often marked by the thickened line of the union of the
two carpels. Seed ovoid, compressed, without albumen, marked on the ventral edge by
the thin raphe; testa membranaceous, light or dark chestnut-brown, of two coats, rarely
produced into a narrow wing; embryo erect; cotyledons flat or slightly convex, much
longer than the superior radicle turned toward the oblong linear pale hilum.
Ulmus, with eighteen or twenty species, is widely distributed through the boreal and
temperate regions of the northern hemisphere with the exception of western North Amer-
ica, reaching in the New World the mountains of southern Mexico and in the Old World
the Sikkim Himalaya, western China, and Japan. Of the exotic species, Ulmus procera
Salisb., the so-called English Elm, and Ulmus glabra, Huds., the Scotch Elm, and several of
its varieties, have been largely planted for shade and ornament in the north Atlantic
states, where old and large specimens of the former can be seen, especially in the neighbor-
hood of Boston.
Ulmus produces heavy, hard, tough, light-colored wood, often diflficult to split. The
tough inner bark of some of the species is made into ropes or woven into coarse cloth, and
in northern China nourishing mucilaginous food is prepared from the inner bark.
Ulmus is the classical name of the Elm-tree.

fluent coats; chalaza colored, close to the minute hilum; embryo curved; cotyledons broad,
foliaceous, conduplicate or rarely flat, variously folded, corrugate, incumbent, or inclosing
the short superior ascending radicle.
Celtis is widely distributed through the temperate and tropical regions of the world,
fifty or sixty species being distinguished.
Trees of the American species are often disfigured by gall-making insects which distort
the buds and cause the production of dark broom-like clusters of short slender branchlets
at the end of the branches.
Celtis was the classical name of a species of Lotus.

western Asia, Indo-China, China, Japan, the Bonin Islands and the mountains of the Indian
Archipelago. Two species occur in North America. The most valuable species, Morus
alba L., a native of China and Formosa, and largely cultivated in many countries for
its leaves, which are the best food of the silkworm, has been planted in large quantities
in the eastern United States; and Morus nigra L., probably a native of Persia, has been
introduced into the southern and Pacific states for its large dark-colored juicy fruit. Morus
produces straight-grained durable light brown or orange-colored valuable wood, and
sweet acidulous and refreshing fruits.
Morus is the classical name of the Mulberry-tree.

nate flower; ovary sessile, erect or oblique, surmounted by the lateral elongated style
crowned by a 2-lobed stigma; ovule suspended from the apex or lateral below the apex
of the cell, anatropous. Fruit mostly immersed in the thickened succulent receptacle,
obovoid or reniform; flesh thin, mucilaginous; nutlet with a flat crustaceous minutely
tuberculate shell. Seed suspended; testa membranaceous; embryo incurved, in thin fleshy
albumen, cotyledons equal or unequal, longer than the incumbent radicle.
Ficus, of which about six hundred species have been described, is largely distributed
through the topics of both hemispheres, the largest number of species being found on the
islands of the Indian Archipelago and the Pacific Ocean. A few species extend beyond
the tropics into southern Florida, Mexico, Argentina, southern Japan and China, the coun-
tries bordering the Mediterranean, the Canary Islands, and southern Africa. Two species
of the section Urostigma with monoecious flowers occur in tropical Florida. Ficus Carica
L., probably a native of the Mediterranean basin, is cultivated in the southern states and
in California for its large sweet succulent fruits, the figs of commerce.

Magnolia with about thirty species is confined to eastern North America, southern
Mexico, and eastern q,nd southern Asia, seven species growing naturally in the United
States. All the parts are slightly bitter and aromatic, and the dried flower-buds are some-
times used in medicine. Several species from eastern Asia and their hybrids producing
flowers before the appearance of the leaves are favorite garden plants in the United States.
The genus is named in honor of Pierre Magnol (1638-1715), professor of botany at
Montpellier.

thick. Wood light, soft, brittle, not strong, easily worked, light yellow or brown, with thin
creamy white sap wood; largely manufactured into lumber used in construction, the interior
finish of houses, boatbuilding, and for shingles, brooms, and woodenware. The intensely
acrid bitter inner bark, especially of the roots, is used domestically as a tonic and stimulant,
and hydrochlorate of tulipiferine, an alkaloid separated from the bark, possesses the prop-
erty of stimulating the heart.
Distribution. Deep rich rather moist soil on the intervales of streams or on mountain
slopes; Worcester County, Massachusetts, to southwestern Vermont (Pownal, Bennington
County), and westward to southern Ontario, southern Michigan and northeastern Mis-
souri, and southward to Orange County (Rock Spring Run), Florida, southern Alabama,
Mississippi and Louisiana, southeastern Missouri and northeastern Arkansas; most abun-
dant and of its largest size in the valleys of the lower Ohio basin, and on the slopes of
the mountains of North Carolina and Tennessee up to altitudes of 5000°.
Often cultivated as an ornamental tree in the eastern states, and in western and central
Europe. A fastigiate form (var. pyramidaia Lav.) is occasionally cultivated.

Crataegus is most abundant in eastern North America, where it is distributed from New-
foundland to the mountains of northern Mexico, and is represented by a large number of
arborescent and shrubby species. A few species occur in the Rocky Mountains and Pacific-
coast regions, and in China, Japan, Siberia, central and southwestern Asia, and in Europe.
The genus is still very imperfectly known in North America, and in the absence of sufficient
information concerning them several arborescent species are necessarily excluded from the
following enumeration. The beautiful and abundant flowers and showy fruits make many
of the species desirable ornaments of parks and gardens, and several are cultivated. Of
exotic species, the Old World Crataegus Oxyacantha L., and C. monogyna Jacq., early intro-
duced into the United States as hedge plants, have now, become naturalized in many places
in the northeastern and middle states. Crataegus produces heavy hard tough close-
grained red-brown heartwood and thick lighter colored usually pale sapwood; useful for
the handles of tools, mallets, and other small articles.
The number of the stamens, although it differs on the same species within certain usually
constant limits, and the color of the anthers, which appears to be specifically constant with
one exception, afford the most satisfactory characters for distinguishing the species in
the different groups.
Cratoegus, from Kpdros, is in reference to the strength of the wood of these trees.

Prunus with about one hundred and twenty species is generally distributed over thfe
temperate regions of the northern hemisphere, and is abundant in North America, eastern
Asia, western and central Asia and central Europe, ranging southward in the New World
into tropical America, and to southern Asia in the Old World. Of the twenty-five or thirty
species which occur in the United States, twenty-two are arborescent in habit. Several of
the species bear fruits which are important articles of human food; many contain in the
seeds and leaves hydrocyanic acid, to which is due their peculiar odor, and the fruit of some
of the species is used to flavor cordials. The wood of Prunus is close-grained, solid, and
durable, and a few of the species are important timber-trees.
Prunus is the classical name of the Plum-tree.

insipid fruit of the arborescent species is eaten by negroes; the seeds contain a considerable
quantity of oil; and the astringent bark, leaves and roots have been used in medicine.
The generic name is from xp^c^^ and ^dXavos, in allusion to the supposed golden fruit of
one of the species.

Acacia with more than four hundred species is widely distributed through Australia,
where it is most largely represented, tropical and southern Africa, northern Africa, south-
western China, the warmer regions of southern Asia, the islands of the south Pacific, trop-
ical and temperate South America, the West Indies, Central America and Mexico to the
southwestern boundaries of the United States where ten or twelve species occur; of these
five are arborescent. Acacia is astringent, and many species yield valuable tan bark.
Gum arabic is produced by different Old World species; many of the species yield hard
heavy durable wood, and some of the Australian Acacias are large and valuable timber-
trees. Many species are cultivated for their graceful foliage and handsome fragrant
flowers.
The generic name, from d/caxfa, relates to the spines with which the branches are usually
armed.

species of trees, shrubs or herbs; of the six North American species two are small trees.
Several of the species produce valuable wood, and from the pods and flower-buds of the
Chinese Sophora japonica L., a dye is obtained used to dye white cloth yellow and blue
cloth green. This tree is often cultivated as an ornament of parks and gardens in northern
China, Japan, the eastern United States, and in western, central, and southern Europe.
The generic name is from Sophera, the Arabic name of some tree with pea-shaped flowers.

cayne to the southern keys, and on the west coast from the neighborhood of Peace River to
Cape Sable; on many of the Antilles and in southern Mexico. Sterile branches collected by
C. T. Simpson in the neighborhood of Cape Sable indicate that a second species occurs in
Florida.

Guaiacum is confined to the New World, and is distributed from southern Florida through
the Antilles, Mexico, and Central America to the Andes of Peru. Seven or eight species
are distinguished.
Guaiacum produces heavy close-grained wood, the cells of the heartwood filled with
dark-colored resin. The lignum-vitae of commerce, largely used for the sheaths of ship-
blocks, mallets, skittle-balls, ten-pin balls, etc., is produced principally by Guaiacum
oficinale L., of the Antilles and South America, and by Guaiacum sanctum L. Guaiacum
resin is a stimulating diaphoretic sometimes used in the treatment of gout and rheuma-
tism.

Amyris is confined to tropical America and northern Mexico. Of the twelve or fourteen
species which have been distinguished two extend into the territory of the United States;
one of these is a small West Indian tree common on the shores of southern Florida, and
the other, Amyris parvifolia A. Gray, a Mexican shrub, grows in Texas near Corpus
Christi, Neuces County, and near the mouth of the Rio Grande. Amyris is fragrant and
yields a balsamic aromatic and stimulant resin, and heavy hard close-grained wood valu-
able as fuel and sometimes used in cabinet-making.
The generic name, from fi^ppa, relates to the balsamic properties of the plants of this
genus.

Simarouba with four species is confined to tropical America, and is distributed from the
coast of southern Florida to Brazil and Guatemala. The plants of this genus contain a
small amount of resin, a volatile oil, and an exceedingly bitter principle, quasin, with
' tonic properties.
The generic name is formed from Simarouba, the Carib name of one of the species.
1. Simarouba glauca DC. Paradise-tree.
Leaves 6'-10' long, glabrous, with a stout petiole 2'-3' in length, and usually 6 pairs of

Picramnia, with about twenty species, is confined to the tropical and subtropical regions
of the New World, one species extending into southern Florida. The bitter principle in
the plants of this genus makes the bark of several of them useful in domestic remedies.
The generic name, from riKpds and ddfivos, is in reference to this bitter principle.

short, rounded, obtuse, with broad-ovate dark red scales slightly scarious on the margins.
Bark of the trunk and large branches 1' thick, glandular dotted, separating freely into
thin papery bright red-brown scales exposing in falling the dark red-brown or gray inner
bark. Wood spongy, very light, exceedingly soft and weak, light brown, with thick sap-
wood, soon becoming discolored by decay. Pieces of the trunk and large branches set
in the ground soon produce roots and grow rapidly into large trees. The aromatic resin
obtained by incisions cut in the trunk was formerly used in the treatment of gout, and in
the West Indies is manufactured into varnish. An infusion of the leaves is sometimes

4. RHUS L.
Trees or shrubs, with pithy branchlets, fleshy roots, and milky sometimes caustie or
watery juice. Leaves unequally pinnate, or rarely simple. Flowers mostly dicecious,
rarely polygamous, white or greenish white, in more or less compound axillary or terminal
panicles, the staminate and pistillate usually produced on separate plants; calyx-lobes
united at base only, generally persistent; disk surrounding the base of the free ovary, co-
herent with the base of the calyx; petals longer than the calyx-lobes, inserted under the
margin of the disk, opposite its lobes, deciduous; stamens 5, inserted on the margin of the
disk alternate with the petals; filaments longer than the anthers; ovary ovoid or subglo-
bose, sessile; styles 3, terminal, free or slightly connate at base, rising from the centre of
the ovary. Fruit usually globose, smooth or covered with hairs; outer coat thin and

transverse; cotyledons foliaceous, generally transverse; radicle long, uncinate, laterally
accumbent.
Rhus is widely distributed, with more than one hundred species, in the extra-tropical
regions of the northern and southern hemispheres. In North America the genus is widely
and generally distributed from Canada to southern Mexico and from the shores of the
Atlantic to those of the Pacific Ocean, with sixteen or seventeen species within the territory
of the United States. Of these, four obtain the habit of small trees. The acrid poisonous
juice of Rhus vernicifera DC, of China, furnishes the black varnish used in China and
Japan in the manufacture of lacquer, and other species are valued for the tannin con-
tained in their leaves or for the wax obtained from their fruit.
The name of the genus is from 'PoOs, the classical name of the European Sumach.

The Holly family with five genera is distributed in temperate and tropical regions of the
two hemispheres. Of the five genera now recognized, only Ilex is important in the number
of species or is widely distributed.
1. ILEX L.
Characters of the family.
Ilex with about one hundred and seventy-five species is found in all tropical and temper-
ate regions of the world with the exception of western North America, Australia, New
Zealand, Tasmania, and New Guinea, the largest number of species occurring in Brazil
and Guiana. Of the thirteen species which inhabit eastern North America, six are trees.
Ilex contains a bitter principle, ilicin, and possesses tonic properties. Ilex paraguariensis
St. Hilaire, of South America, furnishes the mate or Paraguay tea, and is the most useful
of the species. The European Ilex Aquifolium L. is a favorite garden plant, and is some-
times planted in the middle, southern, and Pacific United States.
Ilex is the classical name of the Evergreen Oak of southern Europe.

Sapindus is widely distributed through the tropics, especially in Asia, occasionally ex-
tending into colder regions. About forty species have been distinguished; of these three
are found within the territory of the United States.
Sapindus contains a detersive principle which causes the pulp of the fruit to lather in
water, and makes it valuable as a substitute for soap. The bark, which is bitter and as-
tringent, has been used as a tonic. The seeds of several of the species are strung for chap-
lets and bracelets and are used as buttons.
The generic name, from safo and Indus, refers to the detersive properties and use of the
first species known to Europeans, a native of the West Indies,

Rhamnus with about sixty species is widely distributed in nearly all the temperate
and in many of the tropical parts of the world with the exception of Australasia and the
islands of the Pacific Ocean. Of the five species indigenous to the United States three
attain the size of small trees. The fruit and bark of Rhamnus are drastic, and yield
yellow and green dyes. The European Rhamnus cathartica L., the Buckthorn, has long
been used as a hedge plant in northern Europe, and in eastern North America, where it has
now become sparingly naturalized.
The generic name is from pd/xvos, the classical name of the Buckthorn.

the partitions, 1 or 2-seeded. Seeds obovoid, amphitropous, ascending; seed-coat carti-
laginous, light reddish brown; embryo large, often curved, in fleshy albumen; cotyledons

Tilia with some thirty species is widely distributed in the temperate regions of the north-
ern hemisphere with the exception of western America, central Asia, and the Himalayas.
Tilia produces soft straight-grained pale-colored light wood, largely used for the interior
finish of buildings, in cabinet-making, for the sounding-boards of pianos, wood-carving and
wooden ware, and in the manufacture of paper. The tough inner bark is largely manufac-
tured into mats, cords, fish-nets, coarse cloths, and shoes. Lime-flower oil, obtained by
distilling the flowers of the European species, is used in perfumery. The flowers yield
large quantities of nectar, and honey made near forests of Tilia is unsurpassed in flavor and
delicacy. Many of the species are planted as shade and ornamental trees, and some of
the European species are now common in the gardens and parks of the eastern United
States.

The Pawpaw family with two genera is tropical American and Mexican, a single repre-
sentative of the family reaching the shores of southern Florida.
1. CARICA L.
Short-lived trees, with erect simple or rarely branched stems composed of a thin shell
of soft fibrous wood surrounding a large central cavity divided by thin soft cross partitions
at the nodes, and covered with thin green or gray bark marked by the ring-like scars of
fallen leaf-stalks, and stout soft fleshy roots. Leaves simple, palmately lobed or digitate,
crowded toward the top of the stem and branches, large, flaccid, subpeltately palmately
nerved, and usually deeply and often compoundly lobed. Flowers regular, monoecious
or polygamo-dioecious, white, yellow, or greenish white, in axillary cymose panicles, the
staminate elongated, pedunculate, and many-flowered, the pistillate abbreviated and few
or usually 3-flowered, generally unisexual and dioecious, occasionally polygamo-dioecious,
each flower in the axil of a minute ovate acute bract; calyx minute, 5-lobed, the lobes alter-
nate with the petals; corolla of the staminate flower salverform, gamopetalous, the tube
elongated, 5-lobed, the lobes oblong or linear, contorted in the bud; stamens 10; filaments
free, those of the outer row alternate with the lobes of the corolla and elongated, the others
alternate with them and abbreviated; anthers 2-celled, erect, opening longitudinally, often
surmounted by their slightly elongated connective; ovary rudimentary, subulate; pistillate

flower, calyx minute, 5-lobed, persistent under the fruit; corolla polypetalous, petals 5,
linear-oblong, erect, ultimately spreading above the middle, deciduous; ovary free, sessile,
1-celled or more or less spuriously 5-celled; style 0 or abbreviated; stigmas 5, linear, radiat-
ing, dilated and subpalmately lobed at apex; ovules indefinite, inserted in two rows on the
placenta, anatropous, long-stalked; micro pyle superior; raphe ventral; hermaphrodite
flower, corolla gamopetalous, tubular-campanulate, the lobes erect and spreading or sub-
reflexed; stamens 10, in 2 ranks, or 5; ovary obovoid-oblong, longer than the tube of the
corolla, more or less spuriously 5-celled below. Fruit slightly 5-lobed, 1-celled or more or
less completely 5-celled, filled with soft pulp, many-seeded, that produced from the herma-
phrodite flower long-stalked, pendulous, usually unsymmetric, gibbous, and smaller than
that from the pistillate flower. Seeds ovoid, inclosed in membranaceous silvery white sac-
like arils, occasionally germinating within the fruit; seed-coat crustaceous, closely invest-;
ing the membranaceous inner coat, the outer coat becoming thick, rugose, succulent, and
ultimately dry and leathery; embryo in the axis of fleshy albumen; cotyledons ovate,
foliaceous, compressed, longer than the terete radicle turned toward the minute pale
subbasilar hilum.
Carica with about twenty species is distributed from southern Florida through the West
Indies to southern Brazil and Argentina, and from southern Mexico to Chili. One species
grows probably indigenously in Florida. The milky juice of Carica contains papain, which
has the power of digesting albuminous substances, and the leaves are often used in tropical
countries to make meat tender.
The generic name is formed from the Carib name of one of the species.
1. Carica Papaya L. Pawpaw.
Leaves ovate or orbicular, deeply parted into 5-7 lobes divided more or less deeply into
acute lateral lobes, these secondary divisions entire or rarely lobed, the lowest lobes form-

yellow or orange-colored primary veins radiating from the end of the petiole through the
lobes, and small secondary veins extending to the point of the lateral lobes and connected
by conspicuous reticulate veinlets; petioles stout, yellow, hollow, enlarged and cordate at
base, sometimes becoming 3°-4f° in length before the leaves fall. Flowers often begin-
ning to appear on plants only 3° or 4° high and a few months old, produced continuously
throughout the year, the staminate in clusters on slender spreading or* pendulous peduncles

ovoid to ellipsoid, and obtusely short-pointed, yellowish green to bright orange color; in
southern Florida not more than 4' long and 3' thick, and usually smaller, with a thick skin
closely adherent to the sweet insipid flesh forming a thin layer outside the central cavity;
seeds full and rounded, about y^' long; outer portion of the seed-coat rugose at first when
the fruit is fully grown but still green, ivory-white, very succulent, and usually separable
from the smooth paler chestnut-brown lustrous interior portion, the outer part turning
black as the fruit ripens and becoming adherent to the inner portion closely investing the
thin lustrous light red-brown inner coat.
A short-lived tree, in Florida attaining a height of 12°-15°, with a trunk seldom more
than 6' in diameter; in the West Indies and other tropical countries often twice as large,
with a trunk occasionally dividing into a number of stout upright branches. Bark thin,
light green, becoming gray toward the base of the stem.
Distribution. Florida from the southern shores of Bay Biscayne on the west coast and
of Indian River on the east coast to the southern keys, growing sparingly in rich hum-
mocks; common in all the West Indian islands, in southern Mexico, and in the tropical
countries of South America; now naturalized in most of the warm regions of the world,
where it is universally cultivated for its fruit, which is considered one of the most whole-
some of all tropical fruits, and has been much improved by selection.
XLV. CACTACEiE.
Succulent trees or shrubs, with copious watery juice, numerous spines springing from
cushions of small bristles {areola), and minute caducous alternate leaves, or leafless.
Flowers large and showy, perfect, usually solitary; calyx of numerous spirally imbricated
sepals forming a tube, those of the inner series petal-like; corolla of numerous imbricated
petals, in many series; stamens inserted on the tube of the calyx, very numerous, in several
series, with slender filaments and introrse 2-celled oblong anthers, the cells opening longi-

The Cactus family with twenty genera and a very large number of species is most abun-
dant in the dry region adjacent to the boundary of the United States and Mexico, with a
few species ranging northward to the northern United States and southward to the West
Indian islands, Brazil, Peru, Chili and the Galapagos Islands. Two of the genera have
aiborescent representatives in the flora of the United States.

TREES OF NORTH AMERICA
lower arrested and developed into a cluster of spines surrounded by an elevated cushion or
areola of chaffy tomentose scales. Flowers lateral, elongated, the calyx-lobes forming an
elongated tube, those of the outer ranks adnate to the ovary, scale-like, only their tips free,

Cereus with at least two hundred species inhabits the dry southwestern region of NortL
America, the West Indies, tropical South America, and the Galapagos Islands. Of the nu-
merous species found within the territory of the United States only one assumes the habit
and size of a tree. The fruit of several species is edible, and the ribs of the durable woody
frames of the stems of the large arborescent species are used for the rafters of houses and
for fuel. Many of the species are planted in warm dry countries in hedges to protect cul-
tivated fields, and others are popular garden plants valued for their beautiful flowers,
which are sometimes nocturnal and exceedingly fragrant.
The generic name relates to the candle-like form of the stem of some of the species.

and tapering gradually toward the ends, marked by transverse superficial lines into rings
4'-8' long, representing the amount of annual longitudinal growth, 8-12-ribbed at base
with obtuse ribs 4i'-5' broad, and at summit 18-20-ribbed with obtuse deep compressed ribs,
branchless or furnished above the middle with a few, usually 2 or 3, stout alternate or some-
times opposite upright branches shorter but otherwise resembling the principal stem com-
posed of a thick tough green epidermis, a fleshy covering S'-6' thick saturated with bitter
juice, and a circle of bundles of woody fibres making, with annual layers of exogenous
growth, dense tough elastic columns placed opposite the depressions between the ribs,
f '-3' in diameter and frequently united by branches growing at irregular intervals between
them, the woody frame remaining standing after the death of the plant and the decomposi-
tion of its fleshy covering. Areolae pale, elevated, about ^' in diameter, bearing clusters of
stout straight spines with a large dark fulvous base, sulcate or angled, tinged with red, with
thick stout spines in the centre of each cluster, the 4 basal horizontal or slightly inclined
downward, the lowest being the longest and stoutest and sometimes I5' long and ^^' thick,
the upper shorter, more slender and slightly turned upward, with a row of shorter and
thinner radial spines 12-16 in number surrounding the central group. Wood of the columns
strong, very light, rather coarse-grained, with numerous conspicuous medullary rays, and
light brown tinged with yellow; almost indestructible in contact with the ground, little
affected by the atmosphere and largely used for the rafters of houses, for fences, and by In-
dians for lances, bows, etc. The fruit is consumed in large quantities by Indians.
Distribution. Low rocky hills and dry mesas of the desert; valley of the San Pedro River
through central and southern Arizona to the valley of the Colorado River between Needles
and Yuma, Yuma County, Arizona, and southward in Sonora.
2. OPUNTIA Adans.
Trees or usually shrubs, in the arborescent species of the United States with subcylindric
/5r clavate articulate tuberculate branches, covered with small sunken stomata, and
containing tubular reticulated woody skeletons, and thick fleshy or fibrous roots. Leaves
scale-like, terete, subulate, caducous, bearing in their axils oblong or circular cushion-like
areolae of chaffy or woolly scales terminal on the branches and furnished above the middle
with many short slender slightly attached sharp barbed bristles and toward the base with
numerous stout barbed spines surrounded in some species, except at apex, by loose papery
sheaths. Flowers diurnal, lateral, produced from areolae on branches of the previous year
between the bristles and spines, sessile, cup-shaped; sepals flat, erect, deciduous; corolla
rotate; petals obovate, united at base, spreading; stamens shorter than the petals; filaments
free or slightly united below; anthers oblong; style cylindric, longer than the stamens,
obclavate below, divided at apex into 3-8 elongated or lobulate lobes stigmatic on the
inner face. Fruit sometimes proliferous, covered by a thick skin, succulent and often edi-
ble, or dry, pyriform, globose or ellipsoid, concave at apex, surmounted by the marcescent
tube of the flower, tuberculate, areolate, or rarely glabrous, truncate at base, with a broad
umbilicus at apex. Seeds immersed in the pulpy placentas, compressed, discoid, often
margined with a bony raphe; testa pale, bony, sometimes marked by a narrow darker mar-
ginal commissure; embryo coiled around the copious or scanty albumen; cotyledons large;
radicle thin, obtuse.
Opuntia with many species is distributed from southern New England southward in the
neighborhood of the coast to the West Indies, and through western North America to Chili,
Brazil, and Argentina, the largest number of species occurring near the boundary of the
United States and Mexico. Of the species of the United States at least three attain the
(size and habit of small trees. Cochineal is derived from a scale-insect which feeds on the
760 TREES OF NORTH AMERICA
juices of some of the Mexican species, and the fruit of several species is refreshing and is con-
sumed in considerable quantities in semitropical countries. The large-growing species with
flat branches are employed in many countries to form hedges for the protection of gardens
and fields; and the branches saturated with watery juice are sometimes stripped of their
spines and bristles and fed to cattle.
Opuntia is the classical name of some plant which grew in the neighborhood of the city
of Opus in Bceotia.

World.
1. RHIZOPHORA L. Mangrove.
Trees, with pithy branchlets, thick astringent bark, and adventitious fleshy roots.
Leaves ovate or elliptic, glabrous, petiolate; stipules elongated, acuminate, infolding the
bud, caducous. Flowers perfect, yellow or creamy white, sessile or pedicellate, bibracteo-
late, the bractlets united into an involucral cup, in pedunculate dichotomously or trichoto-
mously branched clusters, the base of their branches surrounded by an involucre of 2 ovate
3-lobed persistent bracts, or l-flowered ; calyx 4-lobed, the lobes acute, coriaceous, ribbed on
the inner surface and thickened on the margins, two or three times longer than the turbi-
nate globose tube, reflexed at maturity, persistent; petals 4, induplicate in the bud, alter-
nate with and longer than the calyx-lobes, inserted on a fleshy disk-like ring in the mouth of
the calyx-tube, involute on the margins, coated on the inner surface with long pale hairs, or
flat and naked, caducous; stamens 8-12; filaments short or 0; anthers attached at the base,
introrse, elongated, connivent, areolate; ovary partly inferior, conic, 2-celled, contracted
into two subulate spreading styles stigmatic at apex. Fruit a conic coriaceous berry sur-
rounded by the reflexed calyx-lobes and perforated at the apex by the germinating embryo.
Seed germinating in the fruit before falling, the apex surrounded by a thin albuminous cup-
like aril; seed-coat thick and fleshy; embryo surrounded by a thin layer of albumen; coty-
ledons dark purple; radicle elongated, clavate, and when fully grown separating from the
narrow exserted woody tube inclosing the plumule and developed from the cotyledons
after the ripening of the fruit.
Rhizophora with three species is widely and generally distributed on the shores of tidal
marshes in the tropical regions of the two hemispheres, one specie reaching those of
southern Florida. It possesses astringent properties; the bark has been used in tan-
ning leather, in dyeing, and as a febrifuge. The wood is hard, durable, and dark-col-
ored. By means of the aerial germination of its seeds and in its power to develop roots
from trunks and branches, Rhizophora is especially adapted to maintain itself on low tidal
shores and is an important factor in protecting and extending them into the ocean. Roots
springing from the stems at a considerable distance above the ground and arching outward
descend into the water and fix themselves in the mud beneath, while roots growing down
from the branches enter the ground and gradually thicken into stems. The fully grown
radicle ready to put forth roots and leaves, and often 10'-12' long, is thicker and heavier
at the root end than at the other, and in detaching itself from the cotyledons and in falling
the heavy end sticks in the mud, while the plumule at the other end, held above the shal-
low surface of the water, soon unfolds its leaves.
The generic name, from pi^a and (p^peip, was used by early authors to designate various
climbing plants with thickened roots.

The widely distributed Cornel family with ten genera, more numerous in temperate than
in tropical regions, has arborescent representatives of the genus Cornus in North America.
1. CORNTJS L. Dogwood.
Trees and shrubs, with astringent bark, opposite or rarely alternate deciduous leaves con-
duplicate or involute in the bud. Flowers small, perfect, white, greenish white or yellow;
calyx-tube minutely 4-toothed, the teeth valvate in the bud; disk pulvinate, depressed in

of the disk; stamens 4, alternate with the petals; filaments slender, exserted; ovary 2-
celled; style exserted, simple, columnar, crowned with a single capitate or truncate stigma;
raphe dorsal. Fruit ovoid or oblong; flesh thin and succulent; nut bony or crustaceous,
2-celled, 2 or sometimes 1-seeded. Seed compressed; embryo straight or slightly incurved.
Cornus with nearly fifty species is widely distributed through the three continents of the
northern hemisphere, and south of the equator is represented in Peru by a single species.
Of the sixteen or seventeen species of the United States four are arborescent. Cornus is
rich in tannic acid, and the bark and occasionally the leaves and unripe fruit are used as
tonics, astringents, and febrifuges. Of exotic species, Cornus mas, L., is often planted in
the eastern states as an ornamental tree, and its edible fruit is used in Europe in preserves
and cordials. The wood of Cornus is hard, close-grained, and durable, and is used in
turnery and for charcoal.
The generic name, from cornu, relates to the hardness of the wood produced by plants of
this genus.

Diospyros, which is chiefly tropical, is widely distributed with more than two hundred
species in the two hemispheres, with a few species extending beyond the tropics into eastern
North America, eastern Asia, southwestern Asia, and the Mediterranean region.
Diospyros produces hard close-grained valuable wood, with dark or black heartwood and
thick soft yellow sapwood. The ebony of commerce is partly produced by difi'erent tropi-
cal species. The fruit is often edible, and some of the species are important fruit-trees in
China and Japan.
The generic name, from Ai6s and trvpSs, is in allusion to the life-giving properties of the
fruit.

1. SYMPLOCOS L'Her.
Characters of the family.
Symplocos with nearly three hundred species inhabits chiefly the warmer parts of Amer-
ica, Asia, and Australia, one species occurring in the southern United States.
Symplocos contains a yellow coloring matter, and the bark and leaves of some species
have medical properties.
The generic name, from Si^/attXokos, relates to the union of the filaments of some of the
species.

States four are arborescent. To this family belong Olea europcea L., the Olive-tree of the
Mediterranean basin, now largely cultivated in California for its fruit, and the Lilacs, For-
sythias. Privets, and Jasmines, favorite garden plants in all countries with temperate cli*
mates.

contrary to the septum, with a dry or woody pericarp produced into an elongated more or
less decurrent wing, usually 1-celled by abortion or sometimes 2 or 3-celled and winged.
Seed solitary in each cell, oblong, compressed, gradually narrowed and rounded at the ends,
filling the cavity of the fruit; seed-coat chestnut-brown.
Fraxinus with thirty to forty species is widely distributed in the temperate regions of the
northern hemisphere, and within the tropics occurs on the islands of Cuba and Java. Of
the eighteen North American species here recognized all, with the exception of Fraxinus
dipetala Hook., of California, are large or small trees.
Fraxinus produces tough straight-grained valuable wood, and some of the species are
large and important timber-trees. The waxy exudations from the trunk and leaves of
Fraxinus Ornus L., of southern Europe and Asia Minor furnish the manna of commerce
used in medicine as a gentle laxative; and the Chinese white wax is obtained from the
branches of Fraxinus chinensis Roxb.
Fraxinus is the classical name of the Ash-tree.

attaining its largest size on the rich bottom-lands of eastern Texas and here often eO^-TO"
high, with a trunk 2°-3° in diameter; on the southern Appalachian Mountains ascending to
altitudes of 2000°-2500°. As it usually grows in the east with its bright green glabrous

occur over the area which it inhabits, but more often westward, with slightly pubescent
leaves and branchlets which may be referred as well to one tree as to the other and make it
impossible to distinguish satisfactorily as species the Green and Red Ash.
Often planted as a shade and ornamental tree in the middle western and occasionally in
the eastern states, but less valuable than the White Ash.

Osmanthus with ten species inhabits eastern North America, the Hawaiian Islands,
Polynesia, Japan, China, and the Himalayas. Osmanthus fragrans Lour., a native of China
and the temperate Himalayas, is cultivated in China for its fragrant minute cream-colored
or yellow flowers used by the Chinese to perfume tea, and is everywhere a favorite garden
plant.
The generic name, from o^ixii and &vdo$, relates to the fragrance of the flowers.

Avicennia with three species is widely distributed on maritime shores of the tropics of the
two worlds, with one species reaching those of the southern United States. Avicennia pro-
duces hard strong wood. The bark is rich in tannic acid, and is used for tanning leather.
The chief value of these trees is in their ability to live on low tidal shores by the structure
of the embryo, which is growing and ready to take root as soon as it falls into the soft mud,
and in the long horizontal roots furnished with short vertical fleshy leafless branches or
aerating roots, forming a close network which holds the soil together and prevents it from
being washed away by outflowing tides, and extends the growth of the tree by numerous
stems which soon form dense thickets.
The generic name is in honor of the illustrious physician of the Orient, Avicenna of
Bokhara (980-1036).

TREES OP NORTH AMERICA
Guettarda with about fifty species is chiefly tropical American, with one species widely
distributed on maritime shores from east tropical Africa to Australia and the islands of the
Pacific Ocean. Of the species found within the territory of the United States two are ar-
borescent. The bark of some of the species is occasionally employed as a tonic and febri-
fuge, and a few species are cultivated in tropical gardens for the delightful fragrance of
their white flowers.
The generic name is in honor of Jean fitienne Guettard (1715-1786), the distinguished
French botanist and mineralogist.

1. SAMBUCUS L. Elder.
Trees or shrubs, with stout branches containing thick white or brown pith, and buds
with several scales. Leaves petiolate, unequally pinnate, deciduous, with serrate or lacini-
ate leaflets, the base of the petiole naked, glandular or furnished with a stipule-like leaf-
let; stipels small, leaf-like, usually setaceous, often 0; stipules small, rudimentary, usually 0

Sambucus with about twenty species is widely and generally distributed through the
temperate parts of North America, Europe, and Asia, and inhabits high mountain ranges
within the tropics, and in Australia, Tasmania, and New Zealand. Of the nine or ten
North American species three are arborescent. Sambucus possesses cathartic and emetic
properties in the bark; the flowers are excitant and sudorific, and the juice of the fruit is al-
terative and laxative. The dried flowers of the European Sambucus nigra L., are used in
the preparation of an aromatic distilled water and in flavoring lard, and the hard and com-
pact wood is made into combs and mathematical instruments. The large pithy shoots of
Sambucus furnish children with pop-guns, pipes, and whistles; and the fruit of some of the
species is cooked and eaten.
Sambucus, the name of the Elder-tree, is believed to have been derived from cajx^iKT], a
musical instrument, probably in allusion to the use of the pithy stems.
